The Namiquipa project consists of three concessions totalling 4,400ha. It includes the La Venturosa silver mine, which was the site of underground mining operations for silver, lead and zinc from 1929 – 1936, 1948 – 1955 and 1990 - 2002. The Company controls the mineralized trend to the north and south of the La Venturosa Mine, where there has previously been only reconnaissance exploration undertaken.

Several high priority targets were flagged during due diligence undertaken for the Namiquipa project acquisition and will form part of a 10,000m drill core program which commenced last week. The Company will keep the market appraised of drilling progress.

In addition the Company is conducting an extensive geophysical program that includes ground magnetic and Induced Polarization (IP) surveys. Anomalies detected during this program are being assessed as the program advances.

The Company also announces that a second drill will be added at its Mount Philp project in Australia in June. Drilling results should be announced during the 2nd and 3rd quarter and the Company plans to initiate a resource calculation by the end of the year.
